The water apple is the least of the small group of somewhat similar fruits of the genus Syzygium (family Myrtaceae). The water apple occurs naturally from southern India to eastern Malaysia. It is commonly cultivated in India, southeastern Asia, and Indonesia. In the Philippines, it grows as though wild in the Provinces of Mindanao, Basilan, Dinagat and Samar. It has never been widely distributed but is occasionally grown in Trinidad and Hawaii. It was introduced into Puerto Rico in 1927 but survived only a few years.
